Utah Highway Patrol troopers and truckers spent five hours rounding up cattle on I-70 Saturday morning after the truck carrying the cattle rolled.

About 80 head of cattle stampeded from the truck after it rolled about 7 a.m. about 14 miles west of Green River. A Carbon County sheriff's dispatcher said that when the cattle were loaded onto a truck at 7 p.m., nine cows were still missing.Driver Robert Halley, 32, of Colorado, was driving along I-70 and attempted to take a rest-area exit when the load of cattle shifted, causing the truck to roll and then slide 400 feet, a dispatcher said.
